Can anyone elaborate on the risk (if any) of datastores with I/O control disabled? Is it a vmware commendation to enable I/O control? Is there any issue in disabling this feature?

Storage I/O Control is a feature of VMware vSphere Enterprise Plus ONLY.

Some datastores and storage does not support Storage I/O Control.

It's Disabled by Default, you have to enable it. So if you have enabled it, and then disabled, the risk is performance could be worse!

There are no real risks, other than you are probably missing out on a datastore which could perform better with it Enabled!

It is recommended to enable!
